What kind of lubricant is in the gearbox of a screwdriver. Lubrication of the gearbox and drills for perforators: proper tool care. Obtaining high-quality lubrication with your own hands

Effective work, safety and long-term use of any equipment depend on the quality and timely care of it. The parts that are subjected to the greatest load require the most attentive attitude to themselves - such as, for example, the angle grinder gearbox.

In the process of using the tool, the structure is subjected to friction, and, accordingly, overheats. Poor-quality grease can, having lost the desired consistency, “leak out” of the mechanism, which will entail additional mechanical and thermal stress. It is also extremely difficult to control the amount of such funds.

The lubricant must be changed if:

"clods", dry and dried particles are found on the inner walls of the body;
the gears of the gearbox are not covered with lubricant in the proper amount;
a year has passed since the last replacement frequent use technology);
replacement of parts of the gearbox, rotor bearings.

Requirements for lubricating fluids for angle grinders

How to lubricate the gearbox of the grinder, the master decides for himself. Universal remedy no - you need to select your liquid for a specific tool. A properly selected lubricant must meet a number of requirements, including:

be resistant to corrosion;
consist of natural components - including in order not to harm the master when inhaling vapors;
reduce the friction force of the gears, and, accordingly, the heating temperature of the tool;
the consistency should be thick enough to stick to the parts, but with a viscosity not higher than 800 Pa s;
the consistency must remain stable, and not change, "melt" or flow out of the mechanism when the temperature rises - minimum temperature dropping +120ºС;
ensure the operation of the tool in the range up to +150 ºС;
the presence of metallic impurities in the composition is not allowed;
tensile strength not less than 120 Pa;
be hydrophobic, have water-repellent properties;
protect the "insides" from dirt, dust.

Overview of lubricants for grinders

If you lubricate the working tool with lithol or grease, saving on materials, it is likely that, in the end, the equipment will refuse to work properly, no matter how high-quality it is.

Some resources claim that making a liquid that satisfies all of the above points is not difficult even at home. In one case, it is recommended to use lubricant for SHURS in combination with MS-20 oil, in another case, it is suggested to use a mixture of Ciatim-221 and TAD-17 substances. Despite numerous positive reviews, in both cases, the consequences can be unpredictable - the manufacturer is unlikely to have taken into account the possibility of refueling the gearbox technical means compositions not reassigned to him.

Foreign companies recommend craftsmen how to lubricate the grinder, offering specially designed ointments. The manufacturer strongly recommends the use of the products specified in the instruction manual. On the Russian market those are really present, but at a fairly high price. In this regard, the question of high-quality lubricants of a domestic manufacturer is acute:

if the original imported lubricant contained molybdenum, you should look for an analogue with the “MoS2” marking;
"NLGI2" - for industrial tools and others working on liquids of the second viscosity class (penetration - 265-295);
"ISOL-XBCHB 2" for the ISO standard;
"DIN 51825-KPF 2 K-20" for DIN standards.

Among Russian lubricants, Interskol materials stand out, long time engaged in the production and service of power tools. Such lubricants, "sharpened" for the features of technology, provide not only first-class operation of the gearbox and meet many stated requirements, but also pleasantly please with the price. So, a tube of lubricant will cost the buyer no more than 100 rubles, while the same lithiol costs only half as much. Whether it makes sense in this case to save, or is it easier to pay a little more, but get a quality product - it's up to each master to decide.

Lubrication Technology

First of all, it is necessary to completely remove the used lubricating fluid - usually, due to the presence of impurities of dust and dirt, it darkens and becomes cloudy. Next, you should carefully check the parts of the tool for traces of lubrication, the cavities of the body - for foreign inclusions, including particles of disintegrated parts. For more effective cleaning angle grinders are recommended to use the liquids used to wash the motor and its parts. Suitable in this number of kerosene and gasoline.

The laying of a new lubricating fluid is carried out before it flows out from reverse side- usually visually it occupies a little less than half the volume of the gearbox. Masters believe that this is the only way to control sufficient filling with material.

If too much lubricant is put in, it will not only find where to “crawl out” in the process of work in the most wrong moment, but will also "interfere" with the instrument. Power will decrease, and energy costs, on the contrary, will increase. However, as a last resort, you can always open the case and remove excess material.

The situation is much more unpleasant with insufficient lubrication. In this case, there is a high probability of poor-quality operation of the gearbox and the tool as a whole. A characteristic “bad” noise is determined, indicating a high voltage of the tool, gear friction.

Now you know how you can lubricate the grinder gearbox. Approach the choice of material for your tool with all responsibility and care. In return, the equipment will repay with a long, uninterrupted service, and even the expensive original lubricant will definitely pay off.

Angle grinders (angle grinders), popularly called grinders, are widely used among tinkerers. With their help House master can not only perform grinding work, but also cut metal, plastic, stone. Angle grinders are produced by various manufacturers, including domestic ones.

The angle grinder is a reliable tool that can work when correct operation and timely replacement of grease and carbon brushes, for a long time.

The right lubricant for the grinder not only extends the life of the tool, but also improves performance.

Knowing the rules for choosing a lubricant for a grinder or preparing it yourself, you can perform Maintenance without contacting the service department.

The main characteristics of the lubricant for angle grinders

In angle grinders, the main unit that is subjected to the greatest stress during operation is a gearbox consisting of helical gears.

The torque generated by the grinder rotor is transmitted from the rotor to the working tool through a small helical gear to a large helical gear. Properly selected lubricant for the gearbox significantly reduces the friction force and heating temperature.

The grinder uses bearings, which also require periodic lubrication. This is especially true for the large helical gear spindle support bearing.

A lubricant is suitable that meets not only the listed requirements, but is also environmentally friendly.

Lubricants for angle grinders must have certain characteristics and must be of the required consistency in properties.

Lubricant for the angle grinder gearbox must have:

viscosity not more than 800 Pa s;
dropping point not less than +120ºС;
tensile strength of at least 120 Pa.

An angle grinder lubricant should not contain mechanical impurities, be resistant to corrosion, be firmly held on lubricated parts, not melt at high temperatures, prevent the formation of scoring at the points of contact of parts and, of course, have water repellency.

In the corner grinder Any company uses two types of plain bearings: bearings for the electric motor and thrust bearings for the gearbox.

The selection of grease for motor bearings is different from the selection of grease for a gearbox bearing. It's all about various conditions work.

Foreign tool manufacturers, including angle grinders, recommend specially designed ointments as lubricants for angle grinders.

One of the most common foreign lubricants is MoS2 NLGI 2 ISOL-XBCHB 2 DIN 51825-KPF 2 K-20.

Let's decipher the label:

MoS2 - indicates the filler material, in this case molybdenum;
NLGI2 - indicates the second viscosity class;
ISOL-XBCHB 2 - belonging to ISO standards;
DIN 51825-KPF 2 K-20 - grease made according to German DIN standards;
The numbers 51825 mean that the grease is type K.

Lubricants produced with such characteristics are quite expensive. There are imported, less expensive lubricants on the Russian market.

Each tool manufacturer, be it Bosch, Makita, Hitachi, DeWalt, Metabo, RedVerg, Interskol, E256, LEPSE, recommends its own lubricants. This is the manufacturer's policy. They insist that the lubricants specified in the instructions be used when performing maintenance. Moreover, non-compliance with these recommendations does not allow warranty repairs.

Grease for gearbox grinder Makita is available in tubes. Its high cost is commensurate with high quality and long service life.

Lubricants of domestic manufacturers for bearings and gearboxes of angle grinders

With the rise in prices for foreign lubricants, lubricants from domestic manufacturers have become especially in demand.

Russian lubricant manufacturers have learned how to produce high-quality lubricants suitable for any tool.

Lubricants for gearboxes of grinders, rotary hammers, and drills have been developed.

Nanotech Metal Plak Electra products are especially popular. The range of lubricants produced by this company allows you to choose the right lubricant for each unit

Lubricant for angle grinder bearings

Three bearings are installed in the design of the angle grinder. Two bearings are mounted on the tool rotor, one bearing is mounted on the shaft of the driven helical gear with a larger diameter.

Angle grinders use bearings already filled with grease. But from improper operation, overheating of the tool, the lubricant flows out.

How to choose the right grease for grinder bearings?

Bearing grease must meet the following requirements:

increase slip;
reduce friction between constituent parts details;
evenly distribute heat and act as a coolant;
prevent corrosion;
protect against ingress of dirt and dust;
work in the required temperature range up to +150С;

The operating conditions of the motor bearings differ from the operating conditions of the gearbox bearing, not only due to temperature requirements, but also due to operating modes, load conditions, frequency and speed of rotation.

Lubricant for motor bearings must have protective properties that prevent dirt, dust and moisture from entering the bearing parts.

The Russian market offers a wide range of foreign lubricants designed for bearings operating in different conditions. But their cost makes us look for cheaper, not inferior in quality, domestic lubricants.

With high water repellency, they have a wide temperature range. The role of a thickener in them is performed by organic and inorganic substances. For sealed bearings, it is best to use TsIATIM-203, VNIINP-242 lubricants.

From pigment lubricants for electric motor bearings, VNIIMP-246 blue grease and VNIINP-235 dark purple ointment have become widespread. First lubrication due to high price less common than the second.

On today's Russian market, they are presented in a wide range of products.

Lubricant for angle grinder gearbox

Lubricant for grinder gearbox is different from lubricant for bearings main feature- increased adhesion. It must hold firmly on the teeth of the gearbox with its large rotation.

In general, the process of lubricating the gearbox in angle grinders occurs due to fine spraying of the lubricant and its suspensions. The gearbox works as if in an oil mist. Therefore, the requirements for lubrication for gearboxes are somewhat different.

In addition to increased adhesion, gear lubricants must have high thermal stability and not melt at elevated temperatures.

Do-it-yourself lubricant for the gear grinder

Listed lubricants domestic production although affordable, they are not always at hand.

Is it possible to make a lubricant for the gearbox of an angle grinder with your own hands

And there is an affirmative answer to this question.

Since the main specifications lubricants for angle grinder gearboxes are presented above, they can be taken as the basis for compiling a lubricant desired characteristics with your own hands.

The basis of a homemade lubricant for gearboxes should be a lubricant with high adhesion. It must be firmly attached to the mating parts.

Lubricant for CV joints has increased adhesion. SHRUS is a hinge in a front-wheel drive car that operates in conditions of increased pollution, impact loads, temperature fluctuations and humidity.

Taking as a basis a lubricant for CV joints, it is necessary to add liquid lubricant (MS-20) to give the mass the desired consistency. MS-20 oil should be applied drop by drop, thoroughly kneading the mass with a homemade mixer.

Good results are obtained by a mixture of a mixture of Ciatim-221 and TAD-17 lubricants, where Ciatim is the basis.

The correct process of stuffing grease in angle grinders

Packing lubricant into the units of an angle grinder has its own rules. You need to know not only the order of its application, but also how much and where to put it.

When to change the lubricant in the grinder

Lubrication on the grinder changes according to the tool maintenance plan, when replacing failed parts of the gearbox or rotor bearings.

Old grease has dirty dark color. This is due to the ingress of foreign particles of metal or dust into it.

How to properly remove old grease in a grinder

Old grease is always removed completely, regardless of its color. There should be no traces of old grease on the parts, and particles of destroyed parts in the cavities of the body.

To remove old grease, you can use various flushing fluids used by motorists to wash the motor and its parts. At home, it is recommended to use kerosene or a solution of kerosene and gasoline.

All parts and their cavities must be thoroughly washed and dried.

The procedure for applying lubricant to the grinder gearbox

The new grease is thoroughly mixed and applied before application. thin layer. The bearings are lubricated by packing. If the lubricant is in a plastic tube, then the neck of the tube is attached to the side separator of the bearing and squeezed out until it flows out of the back side.

How much grease should be used when replacing in the angle grinder gearbox

If the amount of grease in the bearings is controlled by flowing out from the reverse side, then a certain amount of grease is packed into the angle grinder gearbox. Excess grease will leak out during operation. And a small amount of it will not ensure the high-quality operation of the gearbox.

Leave enough grease in the gearbox to cover the gear teeth.

For a guide, apply so much grease that it occupies a little less than half the volume of the gearbox cavity.

Checking the correct application of lubrication to the angle grinder gearbox

The control of the volume of lubricant stuffed into the gearbox is carried out by a trial inclusion of the assembled angle grinder for a short time at idle.

If the gearbox began to warm up, traces of lubricant leakage appear from the seals and gaskets, then the conclusion is clear. You have shifted the lubricant. Open the gearbox housing and remove excess grease. All excess grease will be placed on the gear housing covers. Insufficient amount of lubrication in the gearbox is determined by the increased noise of the gearbox.

With a long the work of the angle grinder the lubricant in the gearbox is distributed on the walls of the housing and loses its properties from external influences.

Having opened the gearbox cover, carefully inspect the condition of the lubricant, the gear tooth profile. If you can, check the contact patch of the gears.

The presence of particles of dry or dried grease in the area of \u200b\u200bthe gearbox or on the housing indicates that the time has come to change the lubricant.

Repair video grinder

Electromechanical manual construction tool household and industrial use with interchangeable nozzles. The tool was invented and created in 1954 in Germany (FRG). The first models of angle grinders that appeared in the USSR at the end of the sixties were angle grinders produced in the Bulgarian city of Plovdiv, from where their name came from, used in Russia to refer to this tool in colloquial speech.

Bulgarian instantly gained immense popularity. Since, certain types of work before its appearance required a significant application of both physical effort and several types of tools for performing one type of operation.

Being, in its essence, a universal device for cutting products and materials of various groups of hardness, as well as coarse abrasive and grinding processing, the angle grinder easily performs the following types of operations:

Cutting ferrous and non-ferrous metals;
Sawing reinforced concrete, natural and artificial stone, ceramics and other materials of this group;

By replacing the saw nozzle with the appropriate disc, the grinder can be sawed wooden crafts and lumber from tree species of different structure.

Also angle grinder is used for the following work after sawing:

Removal of scale and paint from metal and wooden surfaces;
Removal of burrs resulting from sawing materials;
Fine grinding and finishing of planes and hard-to-reach places.

The technical device of the angle grinder

The design of the angle grinder consists of the following elements:

Cases made of metal or plastic;
Reducer and its housing made of aluminum alloys;
Wheel for adjusting the number of rotations;
Start buttons;
Lock buttons for quick change of nozzles;
Clamping nut of the working circle;
The protective cover of the disk and the handle with a variable position on the body;
Electrical cable.

Preventive maintenance of parts and mechanisms of the grinder

In connection with the work performed, in which the occurrence of stone, wood and metal dust is inevitable, as well as its entry into the body of the grinder and settling on the moving mechanical parts of the gearbox, the angle grinder needs periodic preventive inspection and is reduced to the following actions:

Removal of dust and larger fragments of debris from the gearbox housing;
Check the presence of grease in the bearings and on the gears, as well as the integrity of the graphite brushes and replace them if necessary.

Grease for gear grinder Makita (Bosch)

For the reason that the angle grinder is a high-speed, powerful and very hot tool in operating mode, the question of what kind of lubricant to use for the grinder gearbox is very important. We want to immediately highlight the types of lubricants, the use of which for the gearbox (bearings and gears) of angle grinders is not recommended by experts. It:

grease;
lithol.

When choosing which lubricant to lubricate the gearbox of the grinder, it is worth listening to the opinion of professionals in their repair or just long-term users of this tool. Although their opinions will be far from unambiguous.

So, the CV joint lubricants, widely known among motorists, are equally persistently recommended and rejected by experts. Moreover, both sides give quite convincing arguments for and against the use of SHRUS.

We can say with confidence that the lubricant for the gearbox of an angle grinder must meet the following requirements:

Be heat-resistant and not leak out of the gearbox as it heats up;
Increase slip;
Reduce the friction force between contacting, moving elements of parts;
redistribute evenly heat load while simultaneously performing cooling functions;
protect metal parts from corrosion, penetration into the mechanism of dirt and dust.

As expected, tool manufacturers advise using only their own, native spare, consumable parts (brushes) and lubricants.

So, according to Bosch specialists, the lubricant for the Bosch grinder gearbox should be produced by this particular brand. Moreover, it can be successfully used for lubricating gearboxes of angle grinders and other manufacturers. With which the representatives of Makita, Hitachi and so on completely disagree. No doubt, branded lubricants are very different high quality and meet all the declared parameters. If not for one but.

The cost of a can of Makita or Bosch grease (really branded, not a Chinese fake) is comparable to an average Asian-made grinder, which, of course, is very expensive. Naturally, the life of the device directly depends on what kind of lubricant is in the gearbox of the grinder. But on modern market lubricants, you can choose a lubricant that is more affordable and, no less important, not inferior in quality to foreign analogues.

We lubricate the Makita and Bosch angle grinder gearbox with our own hands

action that does not require special efforts and costs. Produced according to the following scheme.

According to the instructions, we disassemble the grinder into its component parts.
Open the gearbox housing.
We remove dirt and dust, as well as the remnants of the previous lubricant.
Distribute new grease evenly throughout the gearbox.
We bring the grinder to its original state.
We start the engine at idle for a while to warm up the lubricant and evenly distribute it over all parts.

Video instruction for changing the lubricant in the Makita angle grinder.

Any power tool contains in its design rotating parts that are subject to increased wear as a result of friction. It is possible to prevent their premature destruction and extend the service life of the tool if timely preventive maintenance of rubbing parts is carried out. In the grinder, the main wear is subject to gear reducer. The harmful effects of friction can be reduced by applying lubricants to the surface of parts. Let's consider what kind of lubricant for the grinder gearbox is better to buy.

With intensive daily use of the grinder, the lubricant in the gearbox should be replaced at least once a year. Often, users do not adhere to certain terms of preventive maintenance of the tool, and routine maintenance is carried out after the appearance of extraneous sounds during operation. This is absolutely not correct method gear maintenance.

Rattle during rotation, rattling indicate that wear has formed on the gears, and they will soon have to be replaced.

A preventive inspection of the gearbox begins with the separation of its casing from the rest of the grinder. To do this, just unscrew the four fixing screws.

On the next photo it can be seen that there is grease in the housing, but it has collected on one side of the housing, and it is not enough.

This is because the angle grinder (angle grinder) is working at high speeds. Under the influence of centrifugal force, oil particles tend to move away from the axis of rotation. At long work the surfaces of the gears become completely dry, and without lubrication, the metal is erased. In this case, it is enough to lubricate the gear teeth with the existing composition, then close the gearbox and work until the next maintenance.

Often in the gearbox you can see grains of oil mixed with dust. During operation, the grinder heats up, and these grains are sintered, particulate matter interfere with the mechanism. This lubricant must be replaced.

How to lubricate the gearbox

The choice of lubricant for the gearbox has some features. The speed of the angle grinder is high, liquid oil will simply fly away from the rotating parts. The thick composition should withstand quite high temperature and don't bake.

Finished lubricant

Power tool manufacturers recommend using special formulations own production. Such recommendations are given, in particular, by Makita and Bosch.

You can buy such funds, but their cost is quite high, and the costs are not always justified. Firm "Interskol" more democratic to the type of materials used. What is the best lubricant? The lubricant for the grinder gearbox must meet certain requirements:

the viscosity of the composition does not exceed 800 Pa * s;
temperature of separation of drops from the main mass is not less than 120°С;
homogeneous composition without the presence of mechanical inclusions;
resistance to moisture.

The industry produces many types of lubricants, including special formulations for use in gearboxes. Best Results show mixtures containing molybdenum disulphide as an extreme pressure additive. If speak about foreign manufacturers, Castrol and Mobil have proven themselves well.

"Mobil" for ease of use places products in tubes that have the shape of a syringe.

From domestic brands, MS-1000, Limol can be noted. The use of grease, litol or Ciatim-221 does not give the desired result.

Homemade mixes

If the required lubricant is not on sale, or if the user considers the price of the product to be unreasonably high, you can try to make the lubricant mixture yourself. There are several recipes using different bases. One of them is common

Transmission oil TAD-17 is added to the container with Ciatim. Whisking continuously, add the oil one drop at a time until the desired consistency is reached. The mixture should adhere well to the parts, not be too thick or run like thin oil.

Another base can be CV joint grease in combination with liquid oil MS-20.

How to lubricate the gearbox

It is not advisable to add the missing amount of oil to the gearbox housing: mixing occurs good composition with the already used one, and the new grease loses its effectiveness faster. Therefore, when the casing of the gearbox and its housing and the cover are removed, the remnants of the old grease are removed. First, use a dry rag, and then wash out the traces with gasoline or kerosene. After the parts have dried, a new lubricant is applied to them, while the gearbox housing is filled with lubricant 2/3 of its volume.

After assembling the grinder, its shaft is scrolled several times by hand to evenly distribute the oil. Rotation should be uniform, without jerks and jamming. After making sure that everything is fine, plug the device into the network and get to work. With timely prevention, the tool will last a long time.

Lubrication for the rotary hammer allows you to extend its service life and make its use more efficient. In order for the effect of the lubricant to bring the expected results, when choosing it, one should take into account not only the characteristics lubricant, but also technical specifications device for which it is intended to be used. When choosing how to lubricate the perforator, one must also keep in mind the fact that various parts of such equipment need different types lubricant.

There is an opinion that the presence of lubricant on the moving elements of the perforator makes it possible to postpone its replacement for a long time. Meanwhile, this opinion is fundamentally erroneous, and in order to change it, it is enough to get acquainted with the principle by which lubricants work.

Why do punch elements need lubrication?

A lubricant, including that used for a perforator, is a viscous substance, the use of which is necessary to reduce the coefficient of friction between structural elements moving relative to each other mechanical device. Thus, the lubricant only reduces friction, but does not eliminate it completely, therefore the lubricating composition is gradually saturated with wear products of rubbing parts - metal dust. As a result, not only the viscosity of the lubricant composition changes, but it itself becomes the cause of more intensive wear of the equipment.

It should be immediately noted that it is the viscosity that is the most important parameter, which you need to focus on when choosing a lubricating composition of a certain type.

How to choose the right lubricant for specific model perforator? First of all, you need to take into account the recommendations of the equipment manufacturer, which must indicate both the type of lubricant required and the frequency of its replacement. It is especially important to focus on such recommendations before the deadline has expired. guarantee period to the perforator. Otherwise, in the event of a device breakdown, you will not be able to use the manufacturer's warranty.

After the warranty period has expired, many owners of rotary hammers begin to use not branded compounds for lubrication, but their cheaper counterparts - lithol or grease. Of course, such lubricants are not capable of harming the structural elements of the perforator, but when using them, it should be borne in mind that they should be replaced much more often.

Gear lubrication

The perforator gearbox is the most complex unit of the device in design, so it requires special attention. It is not so difficult to lubricate the rotary hammer gearbox, but self assembly a previously disassembled assembly can cause serious difficulties. If the hammer drill is still under warranty, then it is best to contact a specialized workshop that provides warranty service for such equipment with a question about lubricating its gearbox.

If the puncher you own is not subject to any warranty obligations or the warranty period for your equipment has already expired, and the authorized service center is far enough away, you can lubricate the gearbox yourself, observing maximum accuracy and care. For this you will need:

a set of locksmith tools with which you will assemble and disassemble the rotary hammer gearbox;
clean rag;
the composition itself for performing lubrication.

"Native" gear lubricant Makita P-08361. Refilled at initial tool assembly and recommended for maintenance

It is better if a branded product specifically designed for equipment of a certain type acts as a lubricant. trademark. So, it can be Makita rotary hammer lubricant or Bosch rotary hammer lubricant. If you don’t have a branded lubricant, but you can’t purchase it, you can also use inexpensive domestic lubricants.

It is very important that you have the instructions for the drill that you are going to lubricate. Naturally, if you are the owner of a Makita or Bosch puncher, this should be an instruction for the equipment of these particular brands.

Having carefully studied the instructions for the puncher, you can proceed to the procedure for lubricating its gearbox.

Before disassembly, the perforator should be well cleaned of dust.
When disassembling the gearbox, it is advisable to immediately remember how the elements of its design are located in it. At the same time, it must be borne in mind that it is not recommended to disassemble and lubricate the gearbox immediately after the end of the use of the perforator. This is explained by the fact that the still hot parts of the gearbox, if a cold lubricating composition gets on them, may lose their physical characteristics.
After all the components of the gearbox have been removed from its housing, they should be thoroughly washed with gasoline or spindle oil and wiped dry.
The inside of the gearbox housing must also be washed, wiped (as far as possible) and allowed to dry completely.
When disassembling the rotary hammer gearbox, you can pay attention to the fact that there is no lubrication on some elements of its design. This only means that such parts do not need lubrication and there is no need to apply it to them.
As mentioned above, it is better to use a branded lubricant for a drill or rotary hammer gearbox, which has a number of advantages. In particular, branded lubricants retain their original characteristics much longer, so they can be used much less often. In addition, the proprietary lubricating composition has such an important quality as water resistance, so it effectively protects the metal parts of the perforator from moisture and, accordingly, from corrosion. As a good alternative to branded lubricants for a rotary hammer or drill gearbox, you can use Metabo oil, the cost of which is quite affordable.
After lubricating all elements, the gearbox must be carefully assembled, following the reverse order.

Caring for a perforator includes not only lubricating its gearbox, but also applying a lubricant to the shank of the drill used.

Before performing this procedure, the tool shank must be thoroughly cleaned. After that, a special lubricant for perforator drills or ordinary lithol is usually used. In addition, if a cartridge is installed on the perforators open type, preferably, after wiping, process its gland, which will provide more reliable protection inside of the device to prevent dust from entering it.

Causes of equipment overheating

Many home craftsmen have a question about how to use a hammer drill so that its gearbox housing does not overheat. First of all, you should find out the cause of too intense heating. One of these reasons may be too a large number of lubrication in the inside of the gearbox, which also negatively affects the performance of the device.

The reason for the intensive heating of the rotary hammer gearbox may also be that insufficient lubricant is supplied to its internal parts. This can happen when the punch is used for too long in chiseling mode.

Another common reason for overheating of the device is that the holes through which cooling air enters the rotary hammer motor are clogged. In such cases, it is necessary to thoroughly clean the hammer drill from dust and switch it to normal drilling mode for a while. When operating in this gentle mode for about half an hour, the temperature of the gearbox housing should decrease.

With proper care of the technical condition of the perforator and compliance with all recommendations for its use, the gearbox housing should not overheat under any operating conditions.

Proper care of a drill with a hammer function

A drill with a hammer function is a hybrid of two types of equipment used to create holes in various materials. Unlike the classic hammer drill, this drill has some design flaws, which makes its maintenance more difficult and not very convenient. These disadvantages include, in particular:

the absence of a special container into which the lubricating composition is poured;
the complexity of servicing the cartridge due to the peculiarities of its structure.

The main care for a drill with the functions of a hammer drill is that after each use, the drill of such equipment (including the tail part) must be well cleaned of drilling waste, and before inserting such a tool into the drill, a small amount should be applied to its shank lubricants (you can use ordinary grease). If the amount of lubricant on the shank is excessive, this will not harm the tool itself and the equipment used, but may adversely affect appearance the surface you are drilling, as excess lubricant will spray from the rotating chuck.

As a rule, drills with hammer functions are purchased for domestic use, since their price is quite affordable, and with their functions when performing simple repair work around the house they do quite well. Despite the fact that these power tools differ in the features mentioned above, caring for a hammer drill does not take much time and does not cause problems even for inexperienced users.

Lubricant selection

Before dealing with the question of how to lubricate the punch, you should get acquainted with the means that can be used to carry out such a procedure. As a rule, the manufacturer indicates the type or brand of lubricant that is best suited to the equipment of a particular model. In any case, such instructions are in the instructions for punchers produced under reputable brands. If there are no such recommendations, you can ask the consultant in the store what kind of lubricant for the punch you are purchasing. fit better Total.

A versatile and relatively inexpensive lubricant that can be used for most modern models perforators, is the oil poured into diesel engines. Compositions based on graphite are actively and quite successfully used to lubricate perforators. Such compositions, in particular, are used for the lubrication of open-type worm gears.
